Errors adding/editing posts and pages

WP – 4.2.2
Theme – Twentyfourteen

I am experiencing a lot of strange issues in the admin console

1. When I click on Posts, I get an error invalid post type
2. When I click on Pages, I see “no pages found”. However, at the top it shows All(16) | Published(14) | Drafts(2)
3. If I view a post and click edit, I can edit the post, but there is no save button. in fact, there is nothing at all in the right column where I would expect to see the option.

I have removed all plugins and themes that I do not use, disabled ALL themes, and reinstalled 4.2.2. Nothing seems to work. I have looked at the error logs and dont see anything logged when this occurs. The site has been running unchanged for quite a while. The site is setup to automatically load the wordpress updates, so that is the only thing I can think of that changed. I have seen some other posts with similar errors, but haven’t had any luck with the fixes.
